IMPRQVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 95,372, dated September28,1869.

To all whom 'it may concern Be it known that I, FREDERICK NIsHWITz, ofBrooklyn, in the county of Kings and State of NewYork, have inventedcertain new and 'useful Improvements in Harvesters, of which thefollowing is a full, clear, and exact de 'scriptionz My inventionrelates to that class of har` vesters known as two-wheeled front-cutmachines, having' a main frame vibrating about a main axle.

The object of my invention is to allow the cutting apparatus, tongue, ordraft-frame and gear-frame, each to vibrate freely, without interferingwith the harmonious co-operation of the mechanism; and

The improvement consists, first, in combin- `ing avibratinggear-frame, avibrating tongue,

a finger-beam, hinged to the tongue or draftframe, andV a vibratinglifting-lever, connected with the rear end of the tongue 'by a loop orlink, which prevents the descent of the front of the gear-frame `below agiven point, but allows it to rise freely; second, in combiningavibratin g main frame and a vibratin g tongue or draft-frame, with acutting apparatus hinged to the tongue or draft-frame only, and by oneend only; third, in combining a vibrating gear-frame, and a vibratingtongue or draftframe, with down-hangers attached to the tongue, and towhich the finger-beam is hinged; fourth, in combining a gear-frame,

' vibrating about the main axle, with a tongue or bracket, to Vwhich thetongue is secured;

seventh, in combining a hinged. cutting appa- `ratus, pivoted todown-hangers or couplingarms, vibrating with the tongue or draft-fra me,with a brace secured to the tongue ordi-aftframe and forming the pivotof the hinge; eighth,i n combining a hinged fingerbeam and tongue ordraft-frame, vibrating in unison, with la lever and thrust-link on the`draftframe, to elevate the divider end of the ngerbeam; ninth, incombining, with a hinged finger-beam, a tilting-lever, vpivoted on thefront couplingarm, and connected with the shoe by a link, forthe purpose`of raising or lowering the divider end of the cutting apparatus; tenth,in combining a hinged ngerbeam and a tilting-lever, mounted on thetongue or draft-frame, with a yielding stop or -flexible connection,which limits the descent of the divider end ot' lthe IingerIbeam;eleventh, in combining the pivoted shoe and its link withatilting-lever, mounted on vthe tongue or draft-frame, and provided witha frictionroller running on the tongue-plate, to relieve the lateralvthrust on thclifting-lever twelfth, in combining a shoe, rigidlysecured to the fin ger-beam, and projectin gin advance thereof,

with a supplementary adjustable spring-shoe, secured by a slot andset-screw, at the heel of the shoe, and with its front end secured onthe pivot on which the shoe vibrates; thirteenth, in arranging agear-frame, vibrating on the driving-axle, and a tongue or draftframevibrating on the gear-frame, with a iinger-beam secured to a long shoe,projecting in advance of the finger-beam and pivoted to down-hangers onthe tongue or draft-frame;

fourteenth, incombininga gear-frame,a tongue and a drivers seat, allvibrating on parallel pivots, with a link connecting the drivers seatand tongue, so that they shall vibrate in unison. v

In the accompanying drawings, all'my improvements are represented asembodied in a single machine. It is obvious, however, that some of theimprovements may be used withoutthe others, and may also be' adapted tomachines differing in construction from that herein shown.

Figure l represents a plan or top view of my improved machine. Fig. 2represents a vertical longitudinal section through the same, at the line.c x of Fig. 1. Fig. 3 represents a view, in elevation, ofthe same, asseen from the rear, with the cutting apparatus foldednp verticali y; andFig. 4, a plan View of the gearframe; Fig. 5, a front view, and Fig. 6 aplan view, of a portion of the pitman andV cutter detached, showing thedetails of their construction.

In this iustance, two main 'driving andsupporting-wheels, A A', turnloosely on a coinmon axle, B, vwith which they are connected bybacking-ratchets of any usual well-known construction. The axle revolvesin pipe-bearings in a cast-metal frame, C, arranged between the wheels,and projecting mostly in front of the axle B. A spur-wheel, D, keyedfast on thc main axle, drives a spur-pinion, d, on a counter-shaft, c,`behind and above the main axle. A spur-wheel, E, on this shaft, drives acorresponding pinion, f, on a sha-ft, f', parallel with and below thecounter-shaft.V A- bevel-wheel, F, on this shaft, drives a correspondingpinion', g, on a crankshaft, G, driving the cutters by a crank and ptmanin the usual way. Y

A tongue, H, is secured by a bolt, h, to a plate, H', upon which it maybe adjusted up `or down by a bolt, h1, taking into one of a series ofholes in the front of the plate. A socket, h2, on the rear end of thisplate, fits on a pivot, I, on the front of the gear-frame, so as toallow the tongue to play freely vertically.

i The tongue extends back of its pivot I, and

its rear end is slotted vertically. A transverse pin in this slot isembraced by a loop, j, attached to an arm, j', on a lifting-lever, J,pivoted on the main axle B.

A pawl,K, pivoted on the lifting-lever, takes into ratchets c, 011 thegear-frame, to hold the gear-frame at any desired elevation. This `pawlis released by backing the lever slightly,

and then shoving down a rod, k, sliding endwise in a groove in thelifting-lever, and bearing on the rear end of thegpawl.

4 The finger-beam L is fastened securely at its heel end to a shoe, L',which extends much further in front of the finger-beam than usual,

and is provided'with lugs 1, between whichl down-hangers orcoupling-arms I I' are pivoted by a rod, l', which is bent up at itsforward end, and bolted to the front end of the .tongue-plate H', thusserving both as a pivot and a brace.

The rear coupling-arm I, it will be observed in this instance, isinserted in a socket in the front of the gear-frame, and is likewisesecured to the rea-r end of the tongueplate, and forms the pivot onwhich the tongue vibrates; The front coupling-arm and brace Z' arelikewise secured to and vibrate with the tongue-plate. By this Inode ofconstruction, the raising and lowering of the tongue correspondinglyvibrates the shoe, andV thus variesthe angle of the guards relatively tothe ground.

A link, m, is pivoted at its lower end to the .shoe L, outside of andbelow its pivot l', while its upper end is attached to a lever, M,vibrating vertically onI the front coupling-arm I'. By drawing back thislever, the link m swings the shoe around its pivot l', and thus liftsthe divider end of the linger-beam.

A friction-roller, m1, on the lever-plate, traverses on thetongue-plate, and prevents the friction of the tiltinglever against thetongue.

A cord, or chain, m2, is secured at one end to the main frame,'and atthe other` to the lever M. This cord lilnits the forward movements ofthe lever M, and, consequently, prevents the divider end ofthefinger-beam from falling below a given point, while leaving it free torise and move the lever backward. When the linger-beam is vertical, thelever M takes into notches m3, on the back of the lifting-lever, and isfirmly held there.

A seat, N, for the driver, Vis mounted on standards n, pivot-ed tovibrate ou the countershaft e. An arm,u', tixed on one ofthe standards,is connected by a link, N', with the tongue-plate in front of and abovethe pivot I. The seat is thus moved back and forth, when the gear-frameis raised or lowered by the hand-lever J.

The shipping-lever is operated by a link, O, coiled around the rod N',so as to be pushed backward or forward by the drivers foot, to throw themechanism into or out of gear.

What I claim as my invention,and desire to secure by Letters Patent, is

1. The combination of a gear-frame, vibrating on the main axle, a tongueor draft-frame, vibrating on the gear-frame, finger-beam hinged tol thetongue or draft-frame, and a liftinglever, connected with the rear endof the tongue by a link, which allows the fingerbeam to rise, but limitsits descent below a given point, substantially as set forth.
